T0 all whom it may concern:

Be it known that I, JOHN F. OCoNNoR,

useful Improvement in Draft-Rigging for Railway-Cars, of which t-he following is a full, clear concise, and exact description, reference being had to the accompanying drawings, forming a part of this specifi- My invent-ion relates to improvements in draft rigging for railway cars.

y The object of my invention is to provide a draft gear having a preliminary spring, and in which the preliminary springoperates independently of the main springs and friction devices of the gear. p

In the-drawings forning apart of this specification, Figure 1 is a Side elevation partly in central longitudinal section of a draft gear embodying my invention. Fig. 2

is a front. end.view thereof. Fig. 3 is a rear end view thereof. Fig. 4 is a perspective view of the preliminary follower. Fig. 5 is a perspective view of the washer employed in said gear.

Referring to the drawings, 6 illustrates a i shell, preferably cylindrical in shape or cir- .cular in cross section, open at its forward end and provided near vits reare'nd with a preferably integral partition 7, in front of which are deposited the main cushioning devices hereinafter' described, and back of which is mounted the preliminary cushion- 1 ing device hereinafter described. The main cushioning members consist of friction l mechanism and the main springs 8, Vpreferably comprising an outer spring 9, and an The friction Mechanism comprises the friction shoes 11, which are preferably three wedge 14, preferably pyramidal in form,

teo to separate the friction shoes, is provi ed with wedging faces 1 5, eqnaling in number the friction shoes, there being an anti-friction roller 18, disposed between each wedging tac-e of the wedge and the adjacent wedginj;`- 'tace ol the friction shoe. The.

Wedge is forwardly provided with a recess 17, to receive the nut 18, of the connecting rod 19, which passes through the wedge and engages the preliminary follower Q0 hereinl i l having a shoulder 23'.

of the partition 7 therein. The said follower is centrally provided with a forwardly extending spindle 26, which passes through a perforation 27- in the partition 7 of the shell, and is provided with a rearwardly opening recess 28, wit-hin which the head 29 of the connecting rod 19 is received; the said connecting rod passing throughk the perforation 30 inthe said spindle. Near. its forward' end the spindle 2G is provided with an annular groove-31, adapted to receive vthe 'i shaped clip or Washer 32 illustrated in F ig. 5 of the drawings. The said washer 32 in preferable construction is provided with an inwardly extended lug 33 which engages within t-he groove 31 ofthe spindle, and an annular portion 34 in front of said lug engaging against the boss at the forward end of the said spindle 26. In preferable constructionthe flange or lug 33 of the washer 32 is of lesserwidth than the annular groove 31 in the spindle QG, leaving 'a space as indicated atI the numeral 37 in Fig. 1 of the drawing to permit the forg ward movement of the spindle without moving thesaid Washer forwardly. Although l it will be apparent that on forward movel nient ofthe said spindle the washer could be forced forwardly employing the inner g spring 10 in connection with the preliminary spring hereinafter described, I prefer that the space 37 substantially corresponds with the space 38 between the front. edge 39 of l the collar of the reliminarv follower and the'partition 7 o the shell in thenormal position of the parts of the gear. l The outer main spring 9 is rearwardly l seated against the rear partition wall 7 of l the shell and around the. washer The outer spring 9 serves to lock the washer 32 securely in osition when the same is keyed to the spindie Q-(S. Seated against the preliminarv follower at Atheir -rear ends and within the collar of Said rear follower are the preliminary springs 40. preferably coniprising an outer spring 41 and an inner after described. The preliminary follower 20 consists of a plate 21, forwardly provided (ill on its extreme forward within the rear chamber 25 of the shell back v liminary inovexnent ofthe lower arel `ofthe shell, and the washer is .then inserted 1' through the forward end ofthe shell and placed in engagement with the said spindle.

3. In a draft gear, a.v friction device in- `oluding a shell, a preliminary follower spring seated between said follower'and shell, the

follower being provided witha projectionand a lock washer slidingyengagingv said p projection within the shell.

4. In aldraft gear combination,av shell friction mechanism and springs within the shell, a preliminary follower, preliminary springs seated between said follower and the S 50 ell, alocking washer, the said 'prelinunar)Y .follower having a forwardly/extended spin-4 dle and groove in said spindle to .receive said washer, whereby 'the .preliminary springs may be held Aunder van initial compression.
